Switch Inputs

AC Switch

Activates when grounded. Normal function is to idle the engine up and delay the AC clutch when activated. Can only be used when you do not have AC. Note that if you want to use the AC Switch itself, then you need to alter the vehicle wiring to ground the other side of the AC Switch.

PS Pressure

Activates when grounded. Normal function is to idle the engine up slightly when the steering is turned. If you have PS then remove the pin from B8 and insert a pin wired to your own switch.

SCS

Activates when grounded. Normal function is to read error codes.

Brake Switch

Activates to 12V. Normal function is to idle up very slightly when the brake is pressed. Remove the factory pin from D2 and insert a pin wired to your own switch.

VTEC Pressure

Activates when grounded. Normal function is to disable VTEC is your oil pressure is very low. Can only be used on non-JDM ECUs. If you have an engine which uses VTP then disable the VTP error check in SManager, remove the factory pin from D6 and insert a pin wired to your own switch.
